如何使intellij idea 8.1.x忽略.gitignore中的项

我喜欢Intellij IDEA 8.1.3中的Git支持。我用它在Linux上做了一些Grails开发。

这个想法似乎忽略了其他文件 .gitignore 喜欢 /tests/reports 等等,但不忽略stacktrace.log。换句话说,stacktrace.log的更改显示在“更改”窗口中

.gitignore文件的内容是:

*.iws
.DS_Store
/out/**

# web application files that are overwritten by "grails upgrade"
#  cf. GRAILS_HOME/scripts/Upgrade.groovy, target( upgrade )
/web-app/WEB-INF

# IDE support files that are overwritten by "grails upgrade"
#  cf. GRAILS_HOME/scripts/CreateApp.groovy, target( createIDESupportFiles )
# to be specific, you could replace "/*" below with your project name,
#  e.g. "foobar.launch" (no slash)
.classpath
.project
.settings
/*.launch
/*.tmproj

# logs
stacktrace.log
/test/reports

# project release file
*.war

/classes

我是否遗漏了一些明显的东西?
